Commercial Building Controls : Building Management Systems : Controllers (Legacy) : W7100G : W7100G1001/U
20-30 Vac Discharge Air/Water temp. ctrl
Overview
Controls discharge water temperature in reciprocating chiller and cooling tower applications.
Features
- The W7100G maintains average discharge water temperature by staging on and off compressors, unloaders of water tower fans as required.
- Provides up to six stages of cooling.
- Use W7101A for expanding up to 10 cooling stages.
- Advanced proportional plus integral microprocessor control algorithm minimizes droop.
- Soft start to minimize compressor cycling during system start up.
- Adjustable minimum on/off timing and time delay between stages of either 30 or 60 seconds.
- Reset of discharge water temperature based on either outdoor air or space sensor signal.
- Use C7170 Sensor for sensing water temperature.
- LEDs indicate which stages of cooling are energized.
- Use S963B Potentiometer for remote set point capability.
